Abstract: A touch screen panel includes a plurality of sensing electrodes arranged in a touch active area, a charge pump circuit for generating an output voltage based on an input voltage and at least one clock signal, a clock signal generator for generating the clock signal, and a touch driver for generating touch driving signals by using the output voltage and applying the touch driving signals to the sensing electrodes. In the touch screen panel, the clock signal and the touch driving signals are synchronized with each other.

Abstract: Disclosed is a touch sensing device, including: a touch panel unit including first electrodes and second electrodes; a driving unit configured to generate a driving signal for detecting a change in capacitance within the touch panel unit; a switching unit configured to transmit the driving signal generated by the driving unit to any one of the first electrodes of the touch panel unit, and receive noise from another one of the first electrodes of the touch panel unit; a noise sensing unit configured to sense the noise received from the switching unit; and a touch sensing unit configured to detect a touch position based on detection signals received through the second electrodes of the touch panel unit and the noise sensed by the noise sensing unit.
